Testimonials

  • Donmar Heating & Cooling

    Thank you very much to everyone at Donmar Company, we are truly happy!

    After researching and interviewing several HVAC companies in my area for a complete HVAC system replacement I decided to select Donmar Company. From my very first conversation with the sales rep I felt like I had finally contacted and knowledgeable and trust worthy company. Instead of trying to push HVAC systems out of date and unreliable like other companies I interviewed I was presented with several intelligent choices and pricing to fit our home and needs. The installation of the system I chose was very professional, clean and educational. The technicians were passionate about their profession and very enjoyable. Donmar Company defines customer service excellence to a higher level and sets the bar to a high level that other companies cannot seem to achieve. Thank you very much to everyone at Donmar Company, we are truly happy!

    They are honest and straightforward with their recommendations and always give us various options.

    We have been with DonMar for years. We trust their work and their service. We recently purchased a new heat pump from them. Installation was professional and so was the service. We have been using them for maintenance on our unit for years and will continue to use them for maintenance. They are honest and straightforward with their recommendations and always give us various options. They call to remind us when service is due which is a huge plus for busy working people.

    It is such a thrill to walk in the door and have the temperature just right.

    I can not thank you and your employees enough. Your customer service is outstanding and everyone that I spoke to or met in person speaks to the nature of your company...to make your customer happy. It is such a thrill to walk in the door and have the temperature just right. It is even better knowing that if I should have any problems, you all will back in a flash to make any adjustments. I wish I knew heating and air conditioning because I would apply for a job with the company. I love nothing better than making people happy by providing the best customer service possible. Should you ever need office assistance, let me know :) Thank you again for everything. I am sure I will hear from someone, when it comes time for my inspections.

    HIGHLY RECOMMEND Donmar Company to anyone with an HVAC issue!!!

    My technician, Paul, did an EXCELLENT job servicing my furnace! He called ahead of time to let me know he was on the way and showed up right on time! Finally a service company that shows up when they say they will!!! He did a comprehensive inspection and explained every step of the process to me. As an engineer, I understood the details of my heat exchanger, but was impressed with his ability to explain everything in a way that a novice could easily understand. I think that helps customers understand their HVAC needs and make decisions with more ease. Paul extensively cleaned my system with the most astute attention to detail! I was impressed! He even cleaned up after himself once the repair and cleaning of the system was complete! Not only was he great at his job, but he was courteous and nice to chat with as he did his work. I am thankful for Paul’s service and HIGHLY RECOMMEND Donmar Company to anyone with an HVAC issue!!! I’m so impressed that I wrote this review minutes after my service was complete–it was that fantastic that it required immediate positive feedback!

    So far we are ecstatic about the improvements. The water heater is working like a champ so far... Really thrilled with that. And really appreciate your crew... They answered all my questions and concerns, the work (at least so far) appears to be impeccable, and the equipment is working great. To date, we have nothing but appreciation and praise for our experience with you and your crew.

    I recommend this company to anyone!

    Exceptional service, they came to my house the same day while other bigger companies where giving me a week or more to come to fix my unit. The technician (George) was extremely knowledgeable and took the time to explain what was wrong, how he was going to fix it, how much it was going to be and offered me multiple alternatives. I recommend this company to anyone. It is so hard to find a trustworthy AC repair company and I think i have finally found it.
